Skin Depth Formula: Skin depth in micro meter is equal to the square root of resistivity ρ (µΩ) in micro ohm divided by the 3.14 times of the signal frequency fo (hz) in frequency and the relative permeability μ r and the permeability (μ o ). Here the permeability can be considered as 4π*10 -7 Where δ = Skin depth in micrometer (μm)

Skin depth defines the distance a wave must travel before its amplitude has decayed by a factor of 1 / e. The skin depth is the reciprocal of the decay constant β. Thus: δ = 1 β = 1 ω ( μ ϵ 2 [ ( 1 + σ 2 ϵ 2 ω 2) 1 / 2 − 1]) 1 / 2 Since β depends on the frequency and the physical properties of the media, so does the skin depth.
